Abstract: A method for applying a polymer film onto an electric conductor joint includes providing an electric conductor joint (2) oriented in a cable direction (A1), providing a roll (32) with a polymer film (31), and securing an end of the polymer film (31) to the electric conductor joint (2). The roll is moved about the electric conductor joint thereby releasing the polymer film from the roll and rotating the roll about an longitudinal center axis. The roll is oriented with the longitudinal center axis parallel with the cable direction during the movement of the roll about the electric conductor joint.

Abstract: A method of manufacturing flexible joints (300) in power cables (100, 200) is described, along with a corresponding system (400, 401). The flexible joints are made by joining the conductors (310, 320) of two cable sections to form a joint section (300) with a region of exposed conductor (22); fitting a mould (402) around at least a portion of the region of exposed conductor (22); and forcing a casting material (409) into the mould by transfer moulding to form an outer layer (350) around the region of exposed conductor (22).

Abstract: A connector (1) for high voltage cables has a metal conductor (11) having a first elongated conductor element having a first end (12a), a second end (12b) and an intermediate section (12c) between the first end (12a) and the second end (12b); an insulating layer (21); and a semiconductive layer (31). The insulating layer is moulded onto the second end (12b) and the intermediate section (12c) of the first elongated conductor element (12) and the insulating layer (21) is provided at a first insulator distance (DI1) from the first end (12a) of the first elongated conductor element (12). The semiconductive layer (31) is provided outside of the insulating layer (21) and the semiconductive layer (31) is provided at a first semiconductor distance (DS1) from the first end (12a) of the first elongated conductor element (12). The first insulator distance (DI1) is shorter than the first semiconductor distance (DS1). The insulating layer (21) is moulded as one single insulating body.

Abstract: A method and system for performing quality checks and positioning of a high voltage accessory component on a high voltage cable during installations and re-using the data from the positioning at a later stage during the lifetime of the cable is described. A 3-dimensional scanner is employed to scan the surface of the high voltage cable and the accessory component to be placed on the cable. The data from the scanner is converted into 3D coordinates and employed by a processor to check for deviations in the quality of the accessory components. The processor then computes and determines the positioning of the accessory component on the high voltage cable. A method for performing quality checks for the subcomponents of the accessory components before positioning of the accessory component during installations is also described.

Abstract: A method and a system is provided for inspecting surfaces and/or interfaces of high voltage and/or medium voltage cable components. The method includes capturing and storing a set of 3-dimensional, 3D, surface geometry measurement data of an area of interest of a surface of the cable or cable component by moving a 3D surface scanner about the cable over the area of interest. The captured 3D surface geometry measurement data are inspected to determine smoothness of the scanned surface, and the smoothness is compared with threshold data to provide a quality report for the scanned surface.

Abstract: A method is provided for determining a quality of a surface of a cable, a part of a cable or an accessory for a cable. The method includes capturing and storing a set of 3-dimensional (3D) surface geometry measurement data of an area of interest of a surface of the cable or cable component by moving a 3D surface scanner about the cable over the area of interest. In an analysis unit, a continuous 3D surface geometry measurement is created of the area of interest by processing measurement data from the 3D surface scanner. The processing includes identifying anomalies in the continuous 3D surface geometry and inspect the captured 3D surface geometry measurement data to discover sub-areas with increased probability for faults. A quality report for the scanned surface is provided.
